All the years of being overweight and inactive have caught up with my left knee, and now it looks as though I am going to have to have arthroscopic knee surgery to "smooth" out the bone. Has anyone had this done? I am scared of going under the knife again. LB was my first surgery, and it went fine, but I am not looking forward to another surgery. Plus, I always hear people say that knee surgery really doesn't even help knee problems. Any thoughts, experiences, opinions?
